Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning device. Background Technology

[0002] As floor scrubbers' brushes become more feature-rich, they integrate more and more components, resulting in increasingly thicker brushes. Consequently, floor scrubber brushes cannot reach some low-ceilinged spaces, such as under sofas, cabinets, and refrigerators, causing dirt to accumulate in these areas and making them difficult to clean. Utility Model Content

[0003] This application provides a cleaning device whose floor brush can clean low-ceilinged spaces with running water, effectively cleaning dirt in low-ceilinged spaces.

[0004] This application provides a cleaning device, comprising:

[0005] The main body, including the main motor used to generate vacuum suction;

[0006] The handle is attached to the top of the body;

[0007] A floor brush is attached to the lower end of the machine body and used to clean the surface to be cleaned. The floor brush includes a floor brush housing, a roller brush module, and at least one drive mechanism. The at least one drive mechanism drives the roller brush module to move relative to the floor brush housing, so that the roller brush module extends at least partially beyond the planar coverage area of ​​the floor brush housing in the axial direction of the roller brush module, and can maintain the extended state to clean the surface to be cleaned; wherein, the height of the roller brush module is lower than the height of the floor brush housing.

[0008] In current cleaning equipment, some roller-type robotic vacuum cleaners extend their rollers to the side when cleaning edges. Because current robotic vacuum cleaners are typically circular, with their rollers located at the rear, the length of the roller is smaller than the diameter of the vacuum cleaner. Therefore, when cleaning edges, the diameter of the central part of the vacuum cleaner contacts the edge first, preventing the roller from cleaning the edge. To achieve a better edge cleaning effect, the roller extends to a position flush with the central edge of the vacuum cleaner. In other cleaning equipment, such as some floor scrubbers, the roller is designed to reciprocate axially. This reciprocating motion is used to scrub away dirt.

[0009] Firstly, the applicant found that current floor scrubbers typically include a housing for their brushes, and some even have clean water and / or wastewater tanks on the brushes. Therefore, the overall thickness of the brushes is generally quite thick. In some areas of a home, such as the recessed area under the kitchen baseboard, the height is often lower than the thickness of the brush, preventing the scrubber from cleaning these areas. This solution separates the roller brush module from the brush housing. Driven by a drive mechanism, the roller brush module can move relative to the brush housing, allowing it to extend at least partially beyond the flat coverage area of ​​the brush housing. Since the thickness of the roller brush module is typically less than the overall thickness of the brush housing, the lower height of the portion extending beyond the housing allows it to clean areas with low ceilings, improving the cleaning capability of the equipment.

[0010] Secondly, the applicant found that current floor scrubbers typically house the roller brush within a brush housing at the front of the brush, and since these brushes are usually square, they cannot thoroughly clean smaller, curved corners in a single pass. Therefore, this solution, by extending the roller brush module, allows for more thorough cleaning of smaller corners, as the square brush housing is no longer strictly limited by the radius of the curved surface.

[0011] Thirdly, some existing robotic vacuum cleaners with side-exit roller function typically only use the roller to exit sideways, scraping dirt from the roller into a wastewater tank on the floor brush using a scraper, without involving a motor to suck up the dirt. Furthermore, existing floor scrubbers that allow the roller to reciprocate axially do not have a suction port that moves with the roller. In contrast, this solution uses a flexible tube assembly at the suction port, allowing it to deform as the roller brush module moves, ensuring the relative position of the roller brush module and the suction port remains the same before and after movement. Thus, even when the extended portion of the roller brush module is cleaning, the cleaning equipment can still guarantee suction power for that area, preventing a decrease in suction power due to the suction port not moving with the extended portion of the roller brush module.

[0012] In one possible implementation, the length of the roller brush module extending beyond the brush housing is 4cm-6cm, preferably 5cm.

[0013] In one possible implementation, the floor brush housing has a first suction port, and the roller brush module has a second suction port. The second suction port is connected to the first suction port through a flexible tube assembly. The flexible tube assembly deforms as the roller brush module moves, so that during the movement of the roller brush module, dirt and cleaning liquid on the surface to be cleaned are always sucked into the first suction port from the second suction port under the action of the main motor.

[0014] In one possible implementation, the roller brush module includes a roller brush frame and a roller brush, a water distributor, a scraper, and a rear scraper connected to the roller brush frame. The roller brush can rotate relative to the roller brush frame. The water distributor is used to supply cleaning fluid to the roller brush. The scraper contacts the roller brush. The rear scraper is located on the rear side of the roller brush in the forward direction and contacts the surface to be cleaned.

[0015] Existing cleaning equipment typically uses a single, side-mounted roller, with a scraper to remove dirt from the roller into a wastewater collection box on the floor brush. However, the roller brush module of this application includes a roller brush frame and a roller brush, a water distributor, a scraper, and a rear scraper connected to the frame. By integrating all these functional components onto the roller brush module, they can all move outside the floor brush housing with the roller brush. This ensures that even after the roller brush is extended, the water distributor continues to supply cleaning fluid to the roller brush, the scraper removes wastewater, hair, fibers, and other dirt from the roller brush, and the rear scraper removes stains adhering to the surface to be cleaned. This ensures that the roller brush maintains continuous, flowing water cleaning even after it is extended, guaranteeing highly efficient cleaning power.

[0016] In one possible implementation, the flexible tube assembly includes: a flexible tube; a first seal that is sealingly connected between a first suction port and a corresponding end of the flexible tube; and a second seal that is sealingly connected between a second suction port and a corresponding end of the flexible tube.

[0017] In this way, the flexible tube has good deformation capacity, meeting the requirements for the roller brush module to move between different positions. Furthermore, the first and second seals respectively seal the first and second suction ports, unaffected by the deformation of the flexible tube, thus sealing the suction channel between the first and second suction ports and preventing leakage from the floor brush.

[0018] In one possible implementation, the flexible tube has a rectangular cross-section, and the communication port on the second seal is a rectangular opening that matches the cross-section of the flexible tube.

[0019] In this way, the cross-sectional area of ​​the flexible tube is increased within the limited space of the roller brush frame, thereby increasing the flow area of ​​the flexible tube. Furthermore, the connection port of the second seal matches the cross-section of the flexible tube, allowing wastewater to flow smoothly from the roller brush module into the flexible tube. This improves the suction efficiency of the floor brush, enabling a high-suction design for the cleaning equipment, and making it more suitable for quickly and thoroughly cleaning heavily soiled, low-ceilinged spaces.

[0020] In one possible implementation, the through-hole on the first seal is an inverted trapezoidal opening, and the opening height of the through-hole is greater than the opening height of the connecting opening.

[0021] This design ensures a better match between the through-hole of the first seal and the suction pipe inside the floor brush, improving the flow of wastewater from the flexible tube into the suction pipe and resulting in a smoother suction process. Furthermore, the more consistent flow area between the through-hole and the flexible tube leads to a more balanced flow rate and pressure of water passing through the flexible tube and the first seal. Additionally, the wider top and narrower bottom of the through-hole increases airflow velocity and enhances the suction power of the main motor. Consequently, the floor brush's suction efficiency is improved, resulting in better suction capabilities for the cleaning equipment.

[0022] In one possible implementation, the first seal and the second seal are integrally formed at both ends of the flexible tube.

[0023] In this way, the flexible tube assembly has better overall integrity, higher structural strength, and a longer service life.

[0024] In one possible implementation, the flexible tube is a stretchable corrugated tube.

[0025] The corrugated tube can extend and retract as the roller brush module moves, requiring less space and facilitating the spatial design of flexible tube components, which helps to reduce the size of the floor brush.

[0026] In one possible implementation, the drive mechanism includes: a drive motor disposed on one of the floor brush housing and the roller brush module; a transmission assembly connected between the other of the floor brush housing and the roller brush module and the drive motor; and a limiting member disposed on the floor brush housing and electrically connected to the drive motor, the limiting member limiting the maximum displacement of the roller brush module.

[0027] In this way, the drive motor drives the transmission assembly to move, and the transmission assembly moves the roller brush module relative to the brush housing. When the limit component detects that the roller brush module has moved to its limit position, the limit component sends a signal to control the drive motor to stop running, thus confining the roller brush module to the limit position.

[0028] In one possible implementation, the transmission assembly includes: a gear connected to the output end of a drive motor; and a rack connected to the roller brush frame of the roller brush module, wherein the rack meshes with the gear, and the gear drives the rack to move.

[0029] In this way, the drive motor drives the gear to rotate, and the gear moves along the rack. The position of the gear remains fixed. As the gear moves along the rack, it drives the rack to move along the extension direction of the rack, thereby driving the roller brush module to move along the extension direction of the rack.

[0030] In one possible implementation, the brush housing has a guide groove, the rack slides along the guide groove, and the rack is connected to the roller brush holder through a connecting part passing through the guide groove.

[0031] In this way, the rack can be mounted on the surface of the drive motor, directly facing the gear, facilitating meshing between the rack and the gear connected to the drive motor. Furthermore, the guide groove on the brush housing not only provides an opening for the rack to connect to the roller brush holder, but also cooperates with the connecting part to guide the movement of the rack.

[0032] In one possible implementation, the connecting portion includes at least two fasteners, each fastener being spaced apart along the length of the rack.

[0033] By using two or more fasteners connected to different points along the length of the rack, the rack and brush holder have multiple connection points, ensuring a secure connection between the rack and brush. Furthermore, these fasteners can move along guide grooves to guide the movement of the rack.

[0034] In one possible implementation, the guide groove includes at least two groove segments spaced apart along the extension direction of the guide groove, and each fastener moves within a corresponding groove segment.

[0035] This reduces the opening area of ​​the guide groove, increasing the strength of the brush housing at the guide groove and improving its reliability. Furthermore, guiding the rack's movement through at least two groove segments provides more precise rack guidance, allowing the rack to stably and reliably remain at its limit position.

[0036] In one possible implementation, the drive mechanism further includes a detection element electrically connected to the drive motor, which detects the operating parameters of the drive motor to control the drive motor to stop operating in the event of an abnormality.

[0037] In this way, the drive motor can be stopped in time in case of abnormality, so as to prevent the drive motor from failing to rotate normally or being in an overloaded state, thus preventing damage to the drive motor and ensuring its service life.

[0038] In one possible implementation, the roller brush frame of the roller brush module has wire holes and pipe holes. The wire harness located in the roller brush frame passes through the wire holes and connects to the ground brush housing. The water pipe connected to the water distributor passes through the pipe holes and connects to the ground brush housing.

[0039] In one possible implementation, both the wire hole and the pipe hole are strip-shaped holes.

[0040] In this way, the strip-shaped holes provide ample space for the wire harness and water pipes to move within the holes as the roller brush module moves, ensuring the reliability of the roller brush module's operation. Attached Figure Description

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] As described in the background section, the thickness of floor scrubbers has increased due to the increasing number of integrated components on their brushes. Consequently, the brushes cannot reach low-lying spaces such as under sofas, cabinets, and refrigerators, leading to long-term buildup of dirt and making these areas difficult to clean.

[0065] In view of this, embodiments of this application provide a cleaning device that separates a roller brush module from a floor brush housing. The roller brush module is connected to the floor brush housing via at least one drive mechanism. Under the drive of the drive mechanism, the roller brush module can move relative to the floor brush housing, allowing it to extend at least partially beyond the planar coverage area of ​​the floor brush housing. Because the portion of the roller brush module extending beyond the floor brush housing is relatively thin, it can access areas with low ceilings for cleaning and can thoroughly clean corners with small radii, thus improving the cleaning capability of the cleaning device in confined spaces.

[0066] The cleaning equipment provided in the embodiments of this application will be described in detail below.

[0067] Figure 1 This is a structural diagram of the cleaning equipment provided in an embodiment of this application in one state. Figure 2 This is a schematic diagram of the cleaning equipment provided in an embodiment of this application in another state. (Refer to...) Figure 1 and Figure 2 As shown in the figure, it should be noted that only the floor brush 10 of the cleaning equipment is shown. The floor brush 10 is the part of the cleaning equipment that comes into contact with the surface to be cleaned. The cleaning equipment uses the floor brush 10 to clean the surface to be cleaned.

[0068] The cleaning equipment also includes a body and a handle (not shown in the figure). The body is the main supporting structure of the cleaning equipment, and it is connected above the floor brush 10, or in other words, the floor brush 10 is connected to the bottom of the body. The body may include a housing and some components housed within the housing. The components within the housing, together with the components within the floor brush 10, form a cleaning fluid supply system and a dirt recovery system to achieve the cleaning function of the cleaning equipment. The handle is connected to the upper end of the body, and the handle may be integrally formed with the housing. The handle is used for the user to grip and control the forward direction of the cleaning equipment.

[0069] The machine body is equipped with a main motor, which is used to generate vacuum suction to remove dirt from the surface to be cleaned.

[0070] like Figure 1 and Figure 2 As shown, the floor brush 10 includes a brush housing 100 and a roller brush module 200. The brush housing 100 is the basic support structure of the floor brush 10 and can also serve as the mounting base for other components of the floor brush 10. The roller brush module 200 includes a roller brush frame 210 and a roller brush 220. The roller brush frame 210 is connected to the brush housing 100, and the roller brush 220 is mounted on the roller brush frame 210. When the cleaning equipment performs cleaning work, the roller brush 220 rolls along the surface to be cleaned to clean the surface.

[0071] The floor brush 10 may also include a booster wheel 600, which may be connected, for example, to the rear side of the floor brush housing 100 in the forward direction. When the floor brush 10 moves on the surface to be cleaned, the booster wheel 600 can roll on the surface to reduce the friction between the floor brush 10 and the surface, thereby reducing the moving resistance of the floor brush 10. Furthermore, the booster wheel 600 can also be driven by a motor to provide moving assistance, further reducing the user's workload.

[0072] In this embodiment, the roller brush module 200 is movably connected to the floor brush housing 100 via the roller brush holder 210, and the roller brush module 200 as a whole can move relative to the floor brush housing 100. Thus, the roller brush module 200 can be separated from the floor brush housing 100, allowing the roller brush module 200 to extend at least partially beyond the planar coverage area of ​​the floor brush housing 100.

[0073] like Figure 1 As shown, the roller brush module 200 is currently positioned directly opposite the ground brush housing 100, and the roller brush module 200 is completely within the planar coverage area of ​​the ground brush housing 100, with the top of the roller brush module 200 obscured by the ground brush housing 100. In this embodiment, the current position of the roller brush module 200 is defined as the normal position, and the current working mode of the roller brush module 200 is defined as the normal working mode.

[0074] When the roller brush module 200 is in its normal position and operating in normal working mode, the roller brush module 200 can clean most of the space that can accommodate the thickness of the ground brush 10.

[0075] like Figure 2 As shown, the roller brush module 200 is currently offset from its position directly opposite the brush housing 100, with a portion of the roller brush module 200 extending beyond the planar coverage area of ​​the brush housing 100. In this embodiment, the current position of the roller brush module 200 is defined as the extended position, and the current operating mode of the roller brush module 200 is defined as the extended operating mode. Furthermore, the portion of the roller brush module 200 extending beyond the planar coverage area of ​​the brush housing 100 is defined as the extended portion of the roller brush module 200.

[0076] When the roller brush module 200 is in the extended position and operating in the extended working mode, the space that the extended portion of the roller brush module 200 can clean is determined solely by the thickness of the roller brush module 200 itself. Freed from the limitations of the floor brush housing 100, the roller brush module 200 has a smaller thickness, allowing its extended portion to reach and clean low spaces such as under sofas, cabinets, and refrigerators. Furthermore, the extended portion of the roller brush module 200 is no longer restricted by the square outline of the floor brush housing 100, enabling cleaning of corners with small radii.

[0077] It should be noted that the extension position of the roller brush module 200 is not limited to one fixed position. After the roller brush module 200 extends out of the brush housing 100, it can remain at different extension positions, which can be selected according to actual needs. For ease of explanation, this embodiment defines the extreme extension position of the roller brush module 200, which is the farthest position where the roller brush module 200 can extend out of the brush housing 100.

[0078] One implementation method is as follows: Figure 2 The diagram illustrates the roller brush module 200 along its axial direction. Figure 2 As shown in the X direction, the roller brush module 200 extends axially beyond the sidewall of the floor brush housing 100. This allows the floor brush 10 to be laterally aligned with the low-lying space to be cleaned, enabling the extended portion of the roller brush module 200 to enter and clean the space. Because the roller brush module 200 extends laterally into the low-lying space, it achieves a larger extension length, and the extended portion can be flexibly adjusted in position, effectively cleaning low-lying spaces.

[0079] For example, when the roller brush module 200 extends axially out of the brush housing and is in its maximum extended position, the length of the portion of the roller brush module 200 extending axially out of the brush housing 100 can range from 4cm to 6cm. This provides sufficient extension length for cleaning many low-ceilinged spaces, such as kitchen baseboards and small-radius curved corners. For instance, the length of the portion of the roller brush module 200 extending axially out of the brush housing 100 can be 4cm, 4.2cm, 4.5cm, 4.8cm, 5cm, 5.2cm, 5.5cm, 5.8cm, or 6cm.

[0080] As another implementation, the roller brush module 200 can also be in a direction perpendicular to the axial direction of the roller brush module 200. Figure 2 As shown in the Y direction, the roller brush module 200 moves towards the front of the floor brush housing 100 (in the forward direction of the floor brush 10), and the entire roller brush module 200 extends beyond the front of the floor brush housing 100. In this way, the front of the floor brush 10 can be aligned with the small space to be cleaned, allowing the entire roller brush module 200 to enter the small space for cleaning. Because the entire roller brush module 200 extends into the small space, the cleaning efficiency of the roller brush module 200 in small spaces is higher.

[0081] In other embodiments, the roller brush module 200 can move both along its axial direction and in a direction perpendicular to its axial direction. This increases the range of motion of the roller brush module 200, allowing its extended portion to move further away from the planar coverage area of ​​the floor brush housing 100. This enables the roller brush module 200 to penetrate deeper into confined spaces, resulting in more thorough cleaning of larger, confined spaces.

[0082] Figure 3 This is an exploded structural diagram of the floor brush provided in an embodiment of this application. (Refer to...) Figure 3 As shown, the floor brush housing 100 of the floor brush 10 may include an upper housing 110 and a lower housing 120. The upper housing 110 is connected to the lower housing 120, and the upper housing 110 and the lower housing 120 together constitute the floor brush housing 100. The lower housing 120 can serve as the main structure of the floor brush housing 100, and the components of the floor brush 10 are mainly installed in the lower housing 120. The floor brush 10 module can be movably connected to the lower housing 120. The upper housing 110 mainly serves as an appearance component. The upper housing 110 can cover the structure on the lower housing 120 and the components installed on the lower housing 120, providing protection for the lower housing 120 and the components on the lower housing 120, and ensuring the overall appearance of the floor brush 10.

[0083] The upper housing 110 may integrate a roller brush cover 111, which is located above the roller brush 220. The roller brush cover 111 covers the upper half of the roller brush 220, leaving only the bottom part of the roller brush 220 that needs to contact the ground exposed. When the cleaning equipment is working, the roller brush 220 rotates at high speed and is accompanied by water spraying and brushing actions. The roller brush cover 111 can form a closed space to prevent sewage and cleaning agents from splashing onto the machine body or the ground, maintaining the cleanliness of the cleaning process. Furthermore, the roller brush cover 111 can protect the roller brush 220, reducing friction between the roller brush 220 and the outside environment. When the cleaning equipment is not working, it prevents external dust and fibrous dirt from adhering to the roller brush 220, extending the service life of the roller brush 220. In addition, the roller brush cover 111 can also prevent users from contacting the high-speed rotating roller brush 220, preventing injury.

[0084] In addition, some roller brush covers 111 have other additional functions. For example, by designing a hot air channel inside the roller brush cover 111, the roller brush 220 is dried, preventing bacterial growth and odor. By using antibacterial materials to make the roller brush cover 111, the growth of surface bacteria is inhibited, further improving hygiene.

[0085] By integrating the roller brush cover 111 into the upper housing 110, the roller brush module 200 is separated from the roller brush cover 111. The protruding part of the roller brush module 200 is not blocked by the roller brush cover 111, which can minimize the thickness of the roller brush module 200 and facilitate the roller brush module 200 to enter a small space.

[0086] Among them, when the roller brush module 200 is Figure 2 When the roller brush module 200 moves axially as shown, the roller brush cover 111 does not affect the movement of the roller brush module 200. At this time, the roller brush cover 111 can be fixedly connected to the upper cover. However, when the roller brush module 200 moves in a direction perpendicular to its axial direction, the roller brush cover 111 blocks the movement path of the roller brush module 200. In this case, the roller brush cover 111 can be connected to the upper housing 110 using a movable connection (e.g., a rotatable connection). When the roller brush module 200 moves forward, the roller brush cover 111 automatically or forced (pushed by the roller brush module 200) flips upward to avoid the roller brush module 200.

[0087] In other examples, when the roller brush module 200 moves in a direction perpendicular to its axial direction, the roller brush cover 111 can also be integrated onto the roller brush module 200, for example, by connecting the roller brush cover 111 to the roller brush holder 210. In this case, the roller brush cover 111 is part of the roller brush module 200, and it is extended synchronously with the roller brush 220. Furthermore, the roller brush 220 can be equipped with a thin roller brush cover 111, which can be made of a high-strength material. While meeting reliability requirements, the roller brush cover 111 has minimal impact on the overall thickness of the roller brush module 200, allowing the roller brush module 200 to still operate in confined spaces for cleaning.

[0088] Figure 4 for Figure 3 A partial exploded view of the floor brush in the image. (Refer to...) Figure 4 As shown, in order to enable the roller brush module 200 to move relative to the floor brush housing 100, the floor brush 10 also includes at least one drive mechanism 300. The drive mechanism 300 is connected between the floor brush housing 100 and the roller brush module 200. For example, the drive mechanism 300 is connected between the lower housing 120 and the roller brush holder 210 to drive the roller brush module 200 to move relative to the floor brush housing 100.

[0089] The drive mechanism 300 may include a drive motor 310 and a transmission assembly 320. The drive motor 310 is mounted on one of the floor brush housing 100 and the roller brush module 200, and the transmission assembly 320 is connected between the other of the floor brush housing 100 and the roller brush module 200 and the drive motor 310. The drive motor 310 drives the transmission assembly 320 to move, and the transmission assembly 320 drives the roller brush module 200 to move relative to the floor brush housing 100. The transmission direction of the transmission assembly 320 may be consistent with the direction in which the roller brush module 200 needs to move, so that the roller brush module 200 moves in the corresponding direction.

[0090] A push-out switch (not shown in the figure) may be provided on the brush housing 100 in conjunction with the drive mechanism 300. The push-out switch may be, for example, a button or a push rod. When the brush module 200 needs to be pushed out, the push-out switch is operated to open it, the drive motor 310 rotates in the forward direction, the brush module 200 extends outward from the brush housing 100 and reaches the push-out position, the drive motor 310 stops, and the brush module 200 can enter the push-out working mode. When the brush module 200 needs to be retracted, the push-out switch is operated again to close it, the drive motor 310 rotates in the reverse direction, the brush module 200 retracts inward from the brush housing 100 and reaches the normal position, the drive motor 310 stops, and the brush module 200 can enter the normal working mode.

[0091] When the roller brush module 200 moves along its axial direction, a drive mechanism 300 can be provided, in which the transmission component 320 has a transmission direction corresponding to the axial direction of the roller brush module 200. When the roller brush module 200 moves along an axial direction perpendicular to its axial direction, a drive mechanism 300 can also be provided, in which the transmission component 320 has a transmission direction corresponding to the axial direction of the roller brush module 200.

[0092] When the roller brush module 200 can move both along its axial direction and in a direction perpendicular to its axial direction, two drive mechanisms 300 can be provided, each equipped with two drive motors 310 and two transmission components 320. Each drive motor 310 drives its corresponding transmission component 320, with the transmission directions of the two transmission components 320 corresponding to the axial direction of the roller brush module 200 and the direction perpendicular to its axial direction, respectively. Alternatively, only one drive mechanism 300 can be provided, which has one drive motor 310. By designing the transmission components 320, one drive motor 310 can drive the roller brush module 200 to move simultaneously along its axial direction and in a direction perpendicular to its axial direction.

[0093] Continue to refer to Figure 4 The drive mechanism 300 may further include a limiting member 330, which is disposed on the brush housing 100. The limiting member 330 may be located at both ends of the movement trajectory of the transmission assembly 320 to limit the maximum displacement of the roller brush module 200. The limiting member 330 is electrically connected to the drive motor 310. When the limiting member 330 detects that the roller brush module 200 has moved to its limit position, the limiting member 330 sends a signal to control the drive motor 310 to stop running, thus limiting the roller brush module 200 to its limit position.

[0094] For example, the limiting member 330 can be a micro switch. When the roller brush module 200 moves to its limit position, the transmission component 320 touches the micro switch. At this time, the micro switch sends a signal, which is transmitted to the control board. The control board sends a control signal to the drive motor 310 to stop the drive motor 310.

[0095] In addition, the drive mechanism 300 may also include a detection element (not shown in the figure), which is also electrically connected to the drive motor 310. The detection element is used to detect operating parameters of the drive motor 310 such as current, temperature, and resistance. In case of obstacles or abnormalities during the ejection of the brush module 200, the detection element can control the drive motor 310 to stop operating and can also trigger an alarm. This is to prevent the drive motor 310 from failing to rotate normally or being in an overloaded state, thus preventing damage to the drive motor 310 and ensuring its service life.

[0096] Combination Figure 3 and Figure 4 As shown, a protective cover 130 may be provided inside the floor brush housing 100, and the protective cover 130 is, for example, connected to the lower housing 120. The protective cover 130 surrounds the outer periphery of the drive mechanism 300, which can isolate the drive mechanism 300 from other components inside the floor brush housing 100. The protective cover 130 can prevent dust, moisture and other foreign objects from entering the drive mechanism 300, thus extending the service life of the drive mechanism 300.

[0097] The following description focuses on the transmission component 320 in the drive mechanism 300, using the axial movement of the roller brush module 200 as an example.

[0098] Figure 5 This is a partial structural diagram of a floor brush in one state, as provided in an embodiment of this application. Figure 6 This is a partial structural diagram of the floor brush in another state, provided in an embodiment of this application.

[0099] Reference Figure 5 and Figure 6 As shown, in one embodiment, the transmission component 320 in the drive mechanism 300 may include a gear 321 and a rack 322. The gear 321 is connected to the output end of the drive motor 310, and the rack 322 meshes with the gear 321. The drive motor 310 drives the gear 321 to rotate, and the gear 321 moves along the rack 322 to realize the movement of the roller brush module 200 relative to the floor brush housing 100. The rack 322 extends in the same direction as the axial direction of the roller brush module 200 to realize the movement of the roller brush module 200 along its axial direction. Alternatively, the rack 322 may extend perpendicularly to the axial direction of the roller brush module 200 to realize the movement of the roller brush module 200 in a direction perpendicular to its axial direction.

[0100] like Figure 5 and Figure 6 As shown, the drive motor 310 is mounted on the brush housing 100, and the rack 322 is connected to the roller brush frame 210 of the roller brush module 200. The position of the gear 321 remains fixed. As the gear 321 moves along the rack 322, it drives the rack 322 to move along the extension direction of the rack 322, thereby driving the roller brush module 200 to move along the extension direction of the rack 322.

[0101] In other examples, the drive motor 310 can also be mounted on the roller brush holder 210 of the roller brush module 200, while the rack 322 is connected to the floor brush housing 100. In this case, the position of the rack 322 remains fixed, and as the gear 321 moves along the rack 322, it drives the gear 321 itself to move along the extension direction of the rack 322, thereby driving the roller brush module 200 to move along the extension direction of the rack 322.

[0102] When the rack 322 is connected to the roller brush holder 210, a guide groove 102 can be provided on the brush housing 100, which connects to the roller brush holder 210. A connecting part 3221 is connected to the rack 322, passing through the guide groove 102 and connecting to the roller brush holder 210, and the connecting part 3221 moves along the guide groove 102. In this way, the rack 322 can be positioned on the side surface where the drive motor 310 is located, and the rack 322 can directly face the gear 321, facilitating meshing between the rack 322 and the gear 321 connected to the drive motor 310. Taking the drive motor 310 mounted on the upper surface of the lower housing 120 as an example, the rack 322 can also be located on the upper surface of the lower housing 120. Furthermore, the guide groove 102 on the floor brush housing 100 not only provides an opening for connecting the rack 322 to the roller brush holder 210, but also cooperates with the connecting part 3221 to guide the movement of the rack 322, ensuring that the rack 322 moves smoothly along the extension direction of the rack 322.

[0103] Reference Figure 5 and Figure 6 With the front side of the brush housing 100 corresponding to the forward direction of the brush 10 as a reference, the right side of the brush housing 100 is located on the left side of the figure, and the left side of the brush housing 100 is located on the right side of the figure. As one embodiment, the figure is illustrated by taking the example of the roller brush module 200 being pushed out toward the right side of the brush housing 100.

[0104] Among them, such as Figure 5As shown, when the roller brush module 200 is in its normal position, the end of the rack 322 facing the right side wall of the brush housing 100 has a gap with the corresponding end of the guide groove 102. At this time, if the end of the rack 322 facing the left side wall of the brush housing 100 contacts the limiting member 330 located on the left side of the brush housing 100, for example, if this end of the rack 322 abuts against the corresponding end of the guide groove 102, it indicates that the roller brush module 200 is in its extreme leftward movement position, and the roller brush module 200 cannot be pushed out towards the left side of the brush housing 100. Figure 6 As shown, when the roller brush module 200 is in the extreme extension position, the rack 322 moves along the guide groove 102 toward the right side of the brush housing 100 to the extreme position. One end of the rack 322 toward the right side wall of the brush housing 100 can contact the limiting member 330 located on the right side of the brush housing 100. For example, this end of the rack 322 can abut against the corresponding end of the guide groove 102.

[0105] In another implementation, the roller brush module 200 can also be pushed out toward the left side of the brush housing 100. In this case, when the roller brush module 200 is in its normal position, there should be a gap between the end of the rack 322 facing the left side wall of the brush housing 100 and the corresponding end of the guide groove 102. The end of the rack 322 facing the right side wall of the brush housing 100 can contact the limiting member 330 located on the right side of the brush housing 100; for example, this end of the rack 322 can abut against the corresponding end of the guide groove 102. When the roller brush module 200 is in its extreme pushed-out position, the rack 322 moves along the guide groove 102 toward the left side of the brush housing 100 to its extreme position, and the end of the rack 322 facing the left side wall of the brush housing 100 can contact the limiting member 330 located on the left side of the brush housing 100; for example, this end of the rack 322 can abut against the corresponding end of the guide groove 102.

[0106] In another implementation, the roller brush module 200 can be pushed out towards either the right or left side of the brush housing 100. In this case, when the roller brush module 200 is in its normal position, there should be a gap between both ends of the rack 322 and both ends of the guide groove 102. When the roller brush module 200 is in its extreme push-out position towards the right side of the brush housing 100, the rack 322 moves along the guide groove 102 towards the right side of the brush housing 100 to its extreme position. One end of the rack 322 facing the right side wall of the brush housing 100 can contact the limiting member 330 located on the right side of the brush housing 100; for example, this end of the rack 322 can abut against the corresponding end of the guide groove 102. When the roller brush module 200 is in the extreme extension position pushed to the left side of the brush housing 100, the rack 322 moves along the guide groove 102 toward the left side of the brush housing 100 to the extreme position. One end of the rack 322 toward the left side wall of the brush housing 100 can contact the limiting member 330 located on the left side of the brush housing 100. For example, this end of the rack 322 can abut against the corresponding end of the guide groove 102.

[0107] Figure 7 This is a partial exploded view of the floor brush provided in an embodiment of this application. (Refer to...) Figure 7 As shown, the connecting portion 3221 connected to the rack 322 may include at least two fasteners 3221a, each fastener 3221a being spaced apart along the length of the rack 322. The fasteners 3221a pass through the guide groove 102 on the brush housing 100 and connect to the roller brush holder 210, thereby connecting the rack 322 to the roller brush holder 210 via the fasteners 3221a. By providing two or more fasteners 3221a connected at different locations along the length of the rack 322, the rack 322 and the roller brush holder 210 have multiple connecting portions 3221, ensuring a secure connection of the rack 322. Furthermore, these fasteners 3221a can move along the guide groove 102 to guide the movement of the rack 322.

[0108] Taking the fastener 3221a as a screw as an example, a stud 211 matching the screw can be provided on the roller brush holder 210. The stud 211 passes through the guide groove 102, and the screw is screwed into the stud 211 to realize the connection between the rack 322 and the roller brush holder 210. The screw and the stud 211 cooperate to make the rack 322 move along the guide groove 102.

[0109] When the connecting portion 3221 includes at least two fasteners 3221a, the guide groove 102 may include at least two groove segments 1021 spaced apart along the extending direction of the guide groove 102. Each groove segment 1021 corresponds to each fastener 3221a, and each fastener 3221a moves within the corresponding groove segment 1021. This reduces the opening area of ​​the guide groove 102, resulting in higher strength of the floor brush housing 100 at the guide groove 102, preventing breakage of the floor brush housing 100 at the guide groove 102, and improving the reliability of the floor brush housing 100. Furthermore, by guiding the movement of the rack 322 through at least two groove segments 1021, the length of each groove segment 1021 can be kept consistent, resulting in more precise guidance of the rack 322. When the rack 322 moves to its limit position, each fastener 3221a abuts against the end of each groove segment 1021, resulting in better stability and higher reliability of the rack 322.

[0110] Figure 8 This is a structural schematic diagram of the roller brush module provided in an embodiment of this application. Figure 9 for Figure 8 Internal structure diagram of the roller brush module. Combined with... Figure 8 and Figure 9As shown, the roller brush module 200 also includes a water distributor 230, which can be integrated into the roller brush holder 210. The water distributor 230 is connected to a clean water tank in the cleaning equipment via a water pipe (not shown). The cleaning solution (e.g., clean water) in the clean water tank is transported to the water distributor 230 via the water pipe, and then distributed to the roller brush 220 by the water distributor 230. A water pump can be connected between the clean water tank and the water pipe to pump the cleaning solution in the clean water tank into the water distributor 230.

[0111] The water distributor 230 can evenly distribute the cleaning solution to all parts of the roller brush 220, ensuring that the roller brush 220 is evenly wetted. This allows the roller brush 220 to be wetted more quickly, thereby improving its cleaning efficiency. Furthermore, the good uniformity of wetting of the roller brush 220 results in a more even cleaning effect on the surface to be cleaned.

[0112] In addition, the spray volume of the water distributor 230 can be controlled according to the degree of dirt on the surface to be cleaned. In areas with stubborn stains or severe dirt, the power of the water pump can be increased, thereby increasing the spray volume of the water distributor 230, allowing the roller brush 220 to be wetted more quickly and thoroughly, enhancing the cleaning effect of the roller brush 220. In areas without stubborn stains and that are relatively clean, the power of the water pump can be reduced, decreasing the spray volume of the water distributor 230, ensuring cleaning efficiency while saving resources.

[0113] In this embodiment, the water distributor 230 is integrated into the roller brush holder 210, and the water distributor 230 moves synchronously with the roller brush holder 210. Thus, regardless of whether the roller brush module 200 is in the normal or extended position, or during the movement of the roller brush module 200 relative to the floor brush housing 100, the water distributor 230 is always aligned with the roller brush 220, enabling it to evenly spray cleaning fluid onto all areas of the roller brush 220. Furthermore, this ensures that the cleaning equipment continuously provides running water to the surface to be cleaned, maintaining a consistently good cleaning effect.

[0114] Combination Figure 8 and Figure 9 As shown, the roller brush module 200 may further include a scraper 240, which can be integrated onto the roller brush holder 210, and the scraper 240 faces the roller brush 220 and contacts the surface of the roller brush 220. The scraper 240 can scrape off foreign objects such as hair and fibers adhering to the surface of the roller brush 220, preventing these foreign objects from being entangled on the roller brush 220 for a long time, thus preventing them from affecting the cleaning effect of the roller brush 220 and ensuring the long-term stable operation of the roller brush 220. At the same time, through the squeezing action of the scraper 240 on the roller brush 220, the wastewater accumulated inside the roller brush 220 can also be scraped out, and then the wastewater is sucked into the wastewater tank of the cleaning equipment for storage by the suction action of the floor brush 10.

[0115] For example, the scraper 240 can be made of a hard material to ensure its reliability. The scraper 240 can also have a comb-like structure to better remove foreign objects such as hair and fibers adhering to the roller brush 220.

[0116] Reference Figure 8 or Figure 9 As shown, the roller brush module 200 may also include a rear scraper 250, which is integrated into the roller brush holder 210. For example, the rear scraper 250 is connected to the roller brush holder 210 by means of bonding, locking, or integral connection. The rear scraper 250 can be located at the lower end of the roller brush holder 210, and is located on the rear side of the roller brush 220 in the forward direction, with the rear scraper 250 in close contact with the surface to be cleaned. After the roller brush 220 cleans the current area, the rear scraper 250 scrapes away residual water in the area. Under the suction action of the floor brush 10, excess water is sucked into the wastewater tank for storage.

[0117] For example, the rear scraper 250 can be made of a flexible material such as rubber or silicone, so that the rear scraper 250 can fit tightly against the surface to be cleaned through deformation. At the same time, it can prevent the rear scraper 250 from wearing down and scratching the surface to be cleaned, and also prevent the surface to be cleaned from damaging the rear scraper 250, thus ensuring the service life of the rear scraper 250.

[0118] In addition, combined Figure 8 and Figure 9 As shown, the roller brush 220 includes a roller brush body 221 and a roller brush motor 222. The roller brush motor 222 can be disposed inside the roller brush body 221, driving the roller brush body 221 to rotate. The roller brush motor 222 is electrically connected to a control board through a wiring harness (not shown in the figure) disposed inside the roller brush frame 210. The control board can be disposed inside the brush housing 100 to control the operation of the roller brush motor 222.

[0119] Figure 10 This is a structural schematic diagram of the roller brush module provided in an embodiment of this application from another perspective. (Refer to...) Figure 10 As shown, the roller brush holder 210 has a wiring hole 212 and a pipe hole 213 on the side facing the brush housing 100. The wiring harness connected to the roller brush motor 222, which is located inside the roller brush holder 210, passes through the wiring hole 212 and extends into the brush housing 100, connecting to the control board inside the brush housing 100. The water pipe connected to the water distributor 230 passes through the pipe hole 213 on the roller brush holder 210 and extends into the brush housing 100, connecting to the clean water tank.

[0120] For the roll brush module 200 that can be launched, the wiring harness and water pipe need to move with the roll brush module 200. Therefore, a certain amount of redundant length needs to be reserved for the wiring harness and water pipe to meet the movement requirements of the roll brush module 200. In this regard, as... Figure 10As shown, the wire hole 212 and pipe hole 213 on the roller brush holder 210 can both be strip-shaped holes. The strip-shaped holes provide a large space for the wire harness and water pipe to move. The wire harness and water pipe can move within the strip-shaped holes as the roller brush module 200 moves, ensuring the working reliability of the roller brush module 200.

[0121] Especially when the roller brush module 200 is pushed out by moving along the axial direction of the roller brush module 200, the wire passage hole 212 and the pipe passage hole 213 can both be extended along the length direction of the roller brush frame 210. In this way, the extension direction of the wire passage hole 212 and the pipe passage hole 213 is consistent with the moving direction of the roller brush module 200, and the wire harness (or water pipe) can better cooperate with the movement of the roller brush module 200 and move within the wire passage hole 212 (or pipe passage hole 213).

[0122] Figure 11 This is a partially exploded structural diagram of a floor brush provided in an embodiment of this application. (Refer to...) Figure 11 As shown, regarding how the suction function of the floor brush 10 is achieved, the floor brush housing 100 has a first suction port 101 on the side facing the roller brush module 200. Correspondingly, the roller brush holder 210 has a second suction port 214 on the side facing the floor brush housing 100 (see...). Figure 10 (As shown). The first suction port 101 and the second suction port 214 are connected by a flexible tube assembly 400. The first suction port 101 of the floor brush housing 100 is connected to the wastewater tank through the suction pipe 500. Under the vacuum suction force generated by the main motor installed on the machine body, the dirt on the surface to be cleaned, along with the cleaning liquid, sequentially passes through the second suction port 214, the flexible tube assembly 400, the first suction port 101, and the suction pipe 500 into the wastewater tank.

[0123] The flexible tube assembly 400 possesses excellent deformation properties, allowing it to deform as the roller brush module 200 moves. Thus, regardless of whether the roller brush module 200 is in its normal or extended position, or during its movement relative to the floor brush housing 100, the flexible tube assembly 400 reliably connects the roller brush module 200 and the floor brush housing 100. Under the action of the main motor, dirt and cleaning fluid on the surface to be cleaned are consistently drawn into the first suction port 101 through the second suction port 214, ultimately pumping the dirt and cleaning fluid into the wastewater tank, achieving wastewater recycling functionality for the cleaning equipment under different conditions.

[0124] By connecting a flexible tube assembly 400 between the first suction port 101 and the second suction port 214, the suction port formed by the flexible tube assembly 400 can deform as the roller brush module 200 moves. This ensures that the relative position of the roller brush module 200 and the suction port remains the same before, after, and during movement. Thus, even when the portion of the roller brush module 200 extending beyond the brush housing 100 is being cleaned, the cleaning equipment can still maintain its suction capacity for that area. The suction force of the cleaning equipment will not decrease in that area because the suction port does not move with the roller brush module 200 after it extends.

[0125] Figure 12 This is a structural diagram of a flexible tube assembly provided in an embodiment of this application. Figure 13 This is a structural diagram of the flexible tube assembly provided in an embodiment of this application from another perspective.

[0126] Reference Figure 12 and Figure 13 As shown, the flexible tube assembly 400 includes a flexible tube 410, a first seal 420, and a second seal 430. The flexible tube 410 serves as a conduit connecting the first suction port 101 of the floor brush housing 100 and the second suction port 214 of the roller brush holder 210. The first seal 420 is disposed at one end of the flexible tube 410 facing the floor brush housing 100 and seals the first suction port 101. The second seal 430 is disposed at one end of the flexible tube 410 facing the roller brush holder 210 and seals the second suction port 214.

[0127] The flexible tube 410 has good deformation capability, meeting the requirement that the first suction port 101 and the second suction port 214 remain connected when the roller brush module 200 moves between different positions. The first seal 420 seals the first suction port 101, and the second seal 430 seals the second suction port 214, thus sealing the suction channel between the first suction port 101 and the second suction port 214. In this way, when the roller brush module 200 moves between different positions, only the flexible tube 410 deforms, while the first seal 420 and the second seal 430 reliably seal the first suction port 101 and the second suction port 214, preventing leakage problems in the floor brush 10.

[0128] For example, the flexible tube 410 can be a retractable corrugated tube. When the roller brush module 200 is in the normal position, the distance between the first suction port 101 and the second suction port 214 is minimal, and the corrugated tube can be in a retracted state. When the roller brush module 200 is in the extended position, the distance between the first suction port 101 and the second suction port 214 increases, and the corrugated tube can be in an extended state. Because the corrugated tube is retractable, it requires less space, which facilitates the spatial design of the flexible tube assembly 400 and helps to reduce the volume of the floor brush 10.

[0129] Of course, the flexible tube 410 can also be a non-extendable flexible tube, designed with sufficient length to meet the movement requirements of the roller brush module 200. When the roller brush module 200 is in the normal position, the flexible tube is in a bent and folded state. When the roller brush module 200 is in the extended position, the flexible tube is in an extended and elongated state.

[0130] When manufacturing the flexible tube assembly 400, the flexible tube 410, the first sealing element 420, and the second sealing element 430 can be fabricated separately, and then the first sealing element 420 and the second sealing element 430 can be connected to both ends of the flexible tube 410 respectively. Alternatively, the first sealing element 420 and the second sealing element 430 can be integrally formed at both ends of the flexible tube 410 after or during the fabrication of the flexible tube 410, so that the flexible tube assembly 400 is formed as a one-piece structure. In this way, the flexible tube assembly 400 has better overall integrity, higher structural strength, and a longer service life.

[0131] like Figure 12 and Figure 13 As shown, the cross-section of the flexible tube 410 can be rectangular. The long side of the cross-section of the flexible tube 410 corresponds to the axial direction of the roller brush 220, and the wide side of the cross-section of the flexible tube 410 corresponds to the height direction of the floor brush 10. In this way, the space occupied by the cross-section of the flexible tube 410 can be completely located within the height space of the roller brush holder 210, and the cross-sectional area of ​​the flexible tube 410 is increased within the limited space of the roller brush holder 210, thereby increasing the flow area of ​​the flexible tube 410. As a result, the suction efficiency of the floor brush 10 is improved, and a high suction power design for the cleaning equipment can be achieved. In particular, when the roller brush module 200 is in the extended working mode to clean small spaces with heavy dirt, it can clean small spaces more quickly and thoroughly.

[0132] Among them, such as Figure 12 As shown, the connecting port 431 on the second seal 430 for communicating with the flexible tube 410 can be a rectangular opening. This rectangular opening matches the cross-section of the flexible tube 410, and for example, it completely overlaps with the wall of the flexible tube 410. In this way, the connecting port 431 on the second seal 430 and the flexible tube 410 have good compatibility, allowing sewage to smoothly enter the flexible tube 410 from the roller brush module 200, avoiding turbulence at the second seal 430, thus ensuring the sewage suction efficiency of the flexible tube assembly 400, and making the flexible tube assembly 400 stronger and with a longer service life.

[0133] Based on this, the second seal 430 can also be roughly rectangular in shape, with a rectangular opening 431 formed on the rectangular second seal 430. This makes the spatial structure of the second seal 430 more reasonable and improves its stress performance. Furthermore, the second suction port 214 formed on the roller brush holder 210 can also be a rectangular opening. The second suction port 214 is a better match for the narrow and long roller brush holder 210, which helps to increase the opening area of ​​the second suction port 214 and enhance the suction power of the floor brush 10.

[0134] like Figure 13 As shown, the through-hole 421 on the first seal 420 for communicating with the flexible tube 410 can be an inverted trapezoidal opening. The suction pipe 500 inside the floor brush housing 100 for communicating with the sewage tank is usually a circular pipe. By designing the through-hole 421 on the first seal 420 as an inverted trapezoidal opening, the through-hole 421 is better matched with the suction pipe 500, which can improve the flow effect of sewage from the flexible tube 410 into the suction pipe 500, making the suction process of the cleaning equipment smoother and the suction efficiency higher.

[0135] Furthermore, the opening height of the through port 421 on the first seal 420 can be greater than the opening height of the connecting port 431 on the second seal 430. In this way, the through port 421 on the first seal 420 can better utilize the height space of the floor brush housing 100, making the flow area of ​​the through port 421 and the flexible pipe 410 more consistent. The flow velocity and pressure of sewage flowing through the flexible pipe 410 and the first seal 420 are more balanced, which is conducive to improving the sewage suction efficiency of the floor brush 10 and the reliability of the flexible pipe assembly 400 is also higher.

[0136] In addition, the inverted trapezoidal through-hole 421, which is wider at the top and narrower at the bottom, facilitates the concentration of airflow towards the top of the through-hole 421. This makes it easier for the main motor to draw air in, and the through-hole 421 helps to increase the gas flow rate, enhance the suction power of the main motor, and thus improve the cleaning equipment's ability to remove dirt.

[0137] Regarding the arrangement of the clean water tank and the wastewater tank within the cleaning equipment, in some embodiments, both the clean water tank and the wastewater tank can be located inside the machine body. The large space inside the machine body allows sufficient room for the clean water tank and the wastewater tank. The clean water tank can be connected to the water distributor 230 inside the roller brush module 200 via the aforementioned water pipe, and the wastewater tank can be connected to the floor brush housing 100 via the aforementioned suction pipe 500.

[0138] In other embodiments, when the space inside the floor brush 10 is large, one of the clean water tank and the wastewater tank can also be located inside the floor brush housing 100. For example, the clean water tank can be integrated into the floor brush housing 100, and only a short water pipe is needed to connect the clean water tank and the water distributor 230. This reduces the weight of the machine body and improves the flexibility of the cleaning equipment. At the same time, it can also increase the weight of the floor brush 10, improve the stability of the floor brush 10, and increase the friction between the roller brush 220 and the surface to be cleaned, thereby improving the cleaning effect of the floor brush 10. In addition, the water circuit layout inside the cleaning equipment is simpler, which can save costs and is also conducive to the layout of other components.
